I’m having an issue with my LibreNMS instance with a Cyberpower PR1500RT2U with the RMCARD205 management card installed. It appears that LibreNMS is using an older MIB that incorrectly identifies a couple values, specifically the Battery Voltage and the Output Current. Both of these should be 0.1 resolution but are currently at 1 resolution. The newer version of the MIB v2.9 shows these changes. I can fix this easily by updating the cyberpower.yaml file and adding the appropriate divisor values, but I wasn’t sure about trying to create my own pull request for this. I know this works with my hardware, but I’m sure there are other devices out there that use the older MIB definition.
For reference, the new MIB is available at : https://www.cyberpowersystems.com/product/software/mib-files/mib-v29/
